[QTI] multiple possible correct answers?

[Devon Copley]

Hi -
 
I'm trying to figure out how to represent a multiple choice question
which could have multiple possible correct answers.  I understand how to
do multiple "and", where it's not marked correct unless all answers are
selected:
 
<responseDeclaration...>
    <correctResponse>
        <value>ChoiceB</value>
        <value>ChoiceD</value>
    </correctResponse>
</responseDeclaration>
 
But what if either Choice B or Choice D is correct?  Is it something
like this:
 
<responseDeclaration...>
    <correctResponse>
        <value>ChoiceB</value>
    </correctResponse>
    <correctResponse>
        <value>ChoiceD</value>
    </correctResponse>
</responseDeclaration>
 
Or is it instead like this:
 
<responseDeclaration...>
    <correctResponse>
        <value>ChoiceB</value>
    </correctResponse>
</responseDeclaration>
<responseDeclaration>
    <correctResponse>
        <value>ChoiceD</value>
    </correctResponse>
</responseDeclaration>
 
Or is it not supported at all?  Any help would be greatly appreciated.
Thanks.
